INKING- DEVICE FOR PRINTING-DRESSES.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed May 18, 1910. Serial No. 562,073.

To all whom it may concern:

Be it known that I, ELMER NIGHOSON, a

citizen of the United States, residing at Grand Rapids, Michigan, have invented certain new and useful Improvements in Inking Devices for Printing-Presses, of which the following is a specification.

This invention relates to improvements in printing presses, and particularly to improvements in the inking devices for print-v ing presses, especiallyfor multi-color work.

This invention relates particularly to an improvement of this class adapted for use on 2. Gordon press, or other similar printing press.

The objects of the invention are to provide a sectional fountain and ink distributing means, whereby different colors, or different varieties of ink, may be made use of on the same form at the same time.

Further objects relate to details of construction and means and methods of supporting and arranging the parts, all of which will appear from the detailed description to follow. I V

I accomplish the objects of myinvention by the devices and means described in the following specification, where I have shown and described a preferred embodiment of my invention.

The invention is clearly defined and pointed out in the claims. I

A structure illustrating a preferred em bodiment of my invention appears in the accompanying drawing, forming a part of this specification, in which: A I V Figure l is a side elevation view of a 7 Gordon press with my improvement in position; Fig. .2 is an enlarged detail'plan 40 view, looking in the direction of the arrow appearing in Fig. 1, of the ink plates and ink fountain, portions being broken away for convenience in illustration. Fig. 3 is a detail plan view, from the same direction,

of the adjustable sections of the ink plate or table. Fig. 4 is an enlarged detail sectional view, taken on a line H of Fig. 2, looking toward the left, showin the brackets for'supporting the fountaln and the roller saddle. Fig. 5 is a sectional view, through one of the fountain sections and rolls, taken on line 55 of Fig. 2, looking toward the left. Fig. 6 is an enlarged detail sectional View, through the ink table,

taken on a line corresponding to line 66 of Fig. 3.

In the drawing, all of the sectional views are taken'looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Referring to the numbered parts of the drawing, the press is of the usual Gordon type, the main frame 1 carrying the other parts. The frame 2 is pivoted thereto at 3, and is driven by a suitable pulley on the shaft 4, and gears 5 and 6 serve to actuate the press through the connection of the pitman 7 to the wrist-pin 8 on the side of the said gear 6, said pitman connecting at the pivot 9 to the frame 2.

10 is the frame of the inking table, which is carried by the bracket 11. The roll saddles 12 carry the form rolls down over the inking table by means of the press arms 13, provided with the usual construction of rod 141 and spring 15, for preserving the tension thereon. The table frame 10 is provided with a central post 16, which is securely clamped in place by abolt or screw 17, as appears in Fig. 6. This post occupies the place usually occupied by the center post of the usual revoluble ink disk. My table is clamped securely in place, so that it does not rotate, but remains in a predetermined fixed position. The distributer sections 18 of any predetermined preferred width are supported on this ink table by their lower ends being beveled and engaging under a suitab beveled under eat at the lower end'iif the table frame. Theupper end is held in place by the beveled strip 20 resting in a suitable depression in the said table, and engaging a corresponding bevel 21 at the upper end of the distributer sections, as clearly appears in Fig. 6. The beveled strip is drawn tight to place by means of a thumb-screw 22, or a plurality of such. Upwardly and forwardly projecting ears 23 are provided at the upper side of this inking table, to which are secured adjustable brackets 24 by means of the securing bolt 26 in the slot 25. These brackets support or carry a rod 27, which,

in turn, carries the several different ink fountains of different size where different widths of color are intended to be distributed to the ink distributer plates of the ink table. The rod 27 is a plain rod shouldered at each end to effectively clamp the said brackets and be supported thereby and hold them in proper spaced relation. A shaft 28 also extends between these brackets, and is provided with similar shoulders at its ends to assist in supporting the brackets in their proper spaced relation and to effectively retain the shaft in position. The shaft is considerably longer than the rod and extends beyond the swing of the side arms of the printing press and carries a ratchet wheel 43, which is acted upon by the ratchet pawl 45, carried on the arm 44, which is connected by a pitman 46 to a crank pin 47 carried and actuated by the pitman 7. This causes the shaft 28 to rotate step-by-step to deliver the ink from the fountains. This structure is very similar or exactly similar to the ratchet wheel and hook or pawl of an ordinary Gordon press.

The ink fountains are made quite similar to the ordinary fountain, containing cast bodies 30, which are adjusted on the shaft 27 by means of the set screw 31. They are separated from each other by a thin plate 32, forming independent and separate side walls for each fountain. The side walls are perforated and embrace the shafts of the fountain rolls.

The fountain rolls 29 do not have separate shafts, but a single shaft, viz., the shaft 28, extends through the entire series ofrolls, there being a roll corresponding to and opposite each narrow fountain. Each fountain roll 29 has, within its bore, one or two pins 29, which fit into key-seats or ways in the shaft 28, and thus they turn with the shaft. These fountains have one-eighth inch thick side walls of brass, with the outer sides of the said walls finished very smooth and flat, thus enabling the ink to be placed upon the vibrator, each color within onefourth inch of an adjoining different color. One or more color vibrator rolls ride the form rolls, such color vibrator roll corresponding to the ink fountain and fountain rol-Ladjacent. Theserolls-distribute the ink and keep each color of ink separate from its adjoining color. The shaft 38of the distributer roll 39 is arranged in a suitable bearing in the saddle and is adapted to reciprocate back and forth, so as to vibrate and evenly distribute the ink which the distributer rolls receive from the fountain rollers.

The shaft 38 is provided at its end with a worm-gear 40, which is engaged by a blade 41, which causes the roll to gradually travel back and forth and thus vibrate and dis tribute the ink. This worm 40 is made shallow at the ends to raise the blade out of engagement and prevent the movement ex- 12 is at each end,see Fig. 4, and puts tension on the shaft 38 of the distributer rolls 39.

The form rolls 3637 are of the usual form and are carried in the saddle 12 in the usual way and receive the ink from the v1- brator roll which distributes the same in proper position upon the roll to deliver the same to the sectional distributer plates 18 of the ink table. These ink fountain sections are of the usual construction of ink fountains and are provided with cast body rollers 29, provided with fountain blades 38 adjustable in relation thereto by means of the set screw 85, the fountain blades being retained in position by the screws 34.

Having described the various parts of my improved multi-color vibrator rolls for printing presses, I will now indicate their operation.

The fountains deliver their ink by the fountain rolls 29 in the usual way when the press is operated. The sectional distributer rolls 29, which vibrate, receive the ink from the fountain rolls and distribute it to the form rolls. The form rolls carry the same to the sectional distributer plates 18, which, as before pointed out, are held in rigid position on the ink table 10 and thence passed down, in the operation of the press, to the form below. They then return and the return movement causes the distributer rolls to vibrate in the opposite direction, owing to the action of the worm gear already referred to. The ink is, therefore, effectively distributed in strips of different colors on the rolls and distributed to different parts of the form, different colors of ink coming as close as one-fourth inch to each other in the actual printing operation without any mixing whatever. This enables a variety of colors to be distributed on the form, so that a letter-head, for instance, can be printed in as many colors as desired, and all the colors printedrat a single operation of the PIGSS, "thl1S @:Qld1Ilg the' necessity of running the matter t'lfmgh several tiiiistosecure color work. have been successfully printed on a single page by this method and means. However, I have only illustrated three sections of fountains of different widths which can be used in this way.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a printing press, of the Gordon type, the combination with the inking table, of detachable distributer strips thereon, retained by suitable beveled portions whereby the form rolls can pass over the same; form rolls carried by the usual roller saddles; a sectional vibrator roll riding the said form rolls; a shaft through the said sectional roll provided with a worm gear; a suitable As high as nine colorsw blade secured to one of said saddles engaging the said worm gear whereby the said shaft is re'ciprocated to properly vibrate the roll to distribute the ink; adjustable brackets carried on posts or cars at the upper side of the said ink table; sectional ink fountains carried on a transverse rod through said bracket; a transverse shaft through said brackets with short fountain rolls corresponding to the said ink fountains to deliver ink therefrom; adjustable fountain blades in the bottom of said fountains for controlling and insuring the delivery of'the ink therefrom; and suitable ratchet mechanisms operated from the press for driving the said fountain rolls, all coacting substantially as described and for the purpose specified.

2. In a printing press of the Gordon type, the combination with an inking table provided with transverse ink distributer strips in spaced relation to each other; of form rolls for passing over the saidinking table to the form by suitable means; a sectional vibrator roll riding the said form rolls the sections thereof corresponding to the ink distributer strips of the said table; and sectional ink fountains corresponding to the said ink distributer strips to deliver ink to the said vibrator roll, coacting for the purpose specified.

3. In a printing press, the combination of an inking table having separate distributer strips thereon; form rolls carried by the usual roller saddles; a sectional vibrator roll riding the said form rolls; a shaft through the said sectional vibrator roll provided with a worm gear; a suitable blade secured to one of the saddles engaging the said worm gear whereby the said shaft is reciprocated and properly vibrates the roll to distribute the ink; and sectional fountains arranged to deliver ink to the said vibrator roll, all arranged and coacting as described and for the purpose specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
